Abstract
Abstract The invention relates to a safety unit for an electric 3-phase circuit for use in, for example, an electric motor. The safety unit comprises three semi-conducting components (1, 2, 3) each of which has a first terminal (4, 6, 8) and a second terminal (5, 7, 9). The safety unit also comprises a support (10) having three contact pins (11, 12, 13) as well as an insertive module (14). The components are secured to the support and electrically contact one of the contact pins (11, 12, 13) via the first terminals (4, 6, 8). Desired electric interconnections between the terminals are established by means of the insertive module (14) via receptive apertures in the support. Such a safety unit exhibits a great sturdiness and a high electrical safety. In addition, the use of specially constructed insertive modules enables a "star" configuration to be converted into a "delta" configuration, and conversely, in a simple manner.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
81 words
A safety unit for an electric 3-phase circuit, said safety unit comprising: three semi-conducting components each provided with a first terminal and a second terminal; a support having three contact pins, each contact pin respectively electrically couplable to a respective first terminal, said support further including a plurality of receptive apertures formed therein; and an insertive module having a plurality of connection pins for selectively electrically interconnecting a respective first terminal and a respective contact pin within said respective receptive apertures.
Claim 2
Dependent Claim
81 words
A safety unit for an electric 3-phase circuit, said safety unit comprising: three semi-conducting components each provided with a first terminal and a second terminal; a support having three contact pins, each contact pin respectively electrically couplable to a respective first terminal, said support further including a plurality of receptive apertures formed therein; and an insertive module having a plurality of connection pins for selectively electrically interconnecting a respective first terminal and a respective contact pin within said respective receptive apertures.
Claim 3
Dependent Claim
38 words
The safety unit as claimed in claim 1, wherein the insertive module comprises three electrical connection pins, which establish an electric interconnection between the second terminals of the components after the module has been inserted into the support.
Claim 4
Dependent Claim
48 words
The safety unit as claimed in claim 1, wherein the insertive module comprises six electrical connection pins, which establish an electric interconnection between a first terminal of a resistor and a second terminal of one of the other components after the module has been inserted into the support.
Claim 5
Dependent Claim
95 words
The safety unit as claimed in claim 1, wherein the insertive module comprises a first insertive portion having three electrical connection pins, so that after the insertion of this first insertive portion of the module into the support the second terminals of the components are electrically interconnected, and in that the insertive module also comprises a second insertive portion having six electrical connection pins, so that after the insertion of the module into the support a first terminal of a component and a second terminal of one of the other two components are electrically interconnected.
Claim 6
Dependent Claim
28 words
The safety unit as claimed in claim 1, wherein the insertive module comprises three electrical connection pins for electrically interconnecting each of the second terminals of the components.
Claim 7
Dependent Claim
40 words
The safety unit as claimed in claim 1, wherein the insertive module comprises six electrical connection pins each respectively interconnectable between a first terminal of one of the three components and a second terminal of another of the three components.
Claim 8
Dependent Claim
60 words
The safety unit as claimed in claim 1, wherein the insertive module comprises a first insertive portion having three electrical connection pins for electrically interconnecting each of the second terminals and a second insertive portion having six electrical connection pins for electrically interconnecting a first terminal of a first component and a second terminal of another of the three components.
